Editing Interactive fiction (section)

===Distribution===
In addition to commercial distribution venues and individual websites, many works of free interactive fiction are distributed through community websites. These include the Interactive Fiction Database (IFDb), The Interactive Fiction Reviews Organization (IFRO), a game catalog and recommendation engine, and the Interactive Fiction Archive.

Works may be distributed for playing with in a separate interpreter. In which case they are often made available in the [[Blorb]] [[package format]] that many interpreters support. A filename ending .zblorb is a story file intended for a Z-machine in a Blorb wrapper, while a filename ending .gblorb is a story file intended for a Glulx in a Blorb wrapper. It is not common but IF files are sometimes also seen without a Blorb wrapping, though this usually means cover art, help files, and so forth are missing, like a book with the covers torn off. Z-machine story files usually have names ending .z5 or .z8, the number being a version number, and Glulx story files usually end .ulx.

Alternatively, works may be distributed for playing in a [[web browser]]. For example, the 'Parchment' project is for web browser-based IF Interpreter, for both Z-machine and Glulx files.

Some software such as [[Twine (software)|Twine]] publishes directly to [[HTML]], the standard language used to create [[web pages]], reducing the requirement for an Interpreter or virtual machine.
